1. Fruits

Fruits are high in liquid-content, helping the body wash out toxins. They are also very easy to digest and are high in antioxidants, nutrients, fiber and important vitamins.

2. Green Foods

Fill your refrigerator with blue green algae, barley, wheatgrass, kale, spinach, spirulina, alfalfa, chard, arugula or other organic leafy greens. These plants will help give a chlorophyll-boost to your digestive tract.
Chlorophyll rids the body of harmful environmental toxins from smog, heavy metals, herbicides, cleaning products and pesticides. They also aid the liver in detoxification.

3. Lemons, Oranges, and Limes

Citrus fruit aids the body in flushing out toxins and jump starts the digestive tract with enzymatic processes. Lemon juice aids the liver in its cleansing processes. To increase detoxification, start each morning with a warm glass of lemon water.
Remember, vitamin C is one of the best detox vitamins around, as it transforms toxins into digestible material. Eat vitamin c foods often to help get more of these benefits.

4. Garlic

This pungent little bulb is one of the best detoxing foods out there. It helps stimulate the liver into producing detoxification enzymes that help filter toxic residues from the digestive system. I recommend adding sliced or cooked garlic to a suitable dish, as this will help aid any detox diet.

5. Broccoli Sprouts

Extremely high in antioxidants, the ability for broccoli sprouts to stimulate the detoxification enzymes in the digestive tract is unparalleled. The sprouts are actually more effective than the fully-grown vegetable.

6. Green Tea

Packed full of antioxidants, green tea washes toxins from the system via its liquid content, but also contains a special type of antioxidant called catechins, which are known to increase liver function.
